Ng4 Unit Of A District. Island Oilfields In Polymer Flooding Project Design And The Injection And Production Management Process

Depending on the higher mobility to improve the oil displacement efficiency and areal sweep efficiency, the polymer solution is injected in the reservoir. During the course of it, the real oil displacement efficiency is influenced as follows:(1) Polymer solution characters such as the basic physical characteristic parameters, the rheological characteristics and the stability etc;(2) The characters of polymer in porous media such as adsorption, molecular weight and strata compatibility, rheological property and resistance coefficient etc;(3)Oil displacement experiment and the testing program, certain volume, heterogeneous inflection etc;(4) The development of the oil reservoir, which includes the degree of communication sedimentary direction and the three great contradictions etc;(5) The coverage degree of the well array;(6)The methods about the subsequent water drive.According to the numerical model to optimize injection project, we strengthen the dynamic analysis, deepen the research of injection law, and strengthen meticulous management. And there are a large number of working sum-ups about these aspects .In it I introduce a kind of polymer flooding inanagement method in ah on-the-spot guidance sense. And it makes a clear effect.
